The transmission failed, shifting is no longer smooth. It hesitates and shakes the entire car, and the car slows down to almost a crawl uphill. I understand this is an issue with Chevrolet Impalas. So now I have an $8200 bill for a problem I was never told about, and that GM knew that it…
The transmission failed, shifting is no longer smooth. It hesitates and shakes the entire car, and the car slows down to almost a crawl uphill. I understand this is an issue with Chevrolet Impalas. So now I have an $8200 bill for a problem I was never told about, and that GM knew that it existed. So, yes, the issue has been identified, reproduced and confirmed by the dealer. The warning light came on when the issue happened, so it was already too late. The issue began with just over 65,000 miles. So I have a 2018 Impala in almost perfect condition in need of an $8200 before taxes, transmission replacement. I would like some help from the NHTSA, like requiring GM to pay for the repairs. Thank You very much.

Passenger side front seat. When occupied, airbag sensor located inside the seat is malfunctioning. My husbands safety is at risk when he's in the car. He tries moving the seat up, back, etc. Sometimes works and the airbag sensor works. We are fearing that if there were any accident or need, that his life would be in danger if the airbag didn't deploy. This shouldn't be at the consumers expense as this is a safety issue. This has been ongoing for over 6 months.

I was sold a used car w/ undisclosed accidents. Had many issues within first few weeks. Had transmission cooler lines replaced after they burst. Radiator, compressor, condenser, and much more. Then the Airbag light came on. Dealership said connectors were bad. Fixed it. Light came on again.took it in to dealership. They had it for over two weeks. The GM for all the dealerships Told me the vehicle was not unsafe and told me lies. But the service girl confessed she no longer had access to my vehicle or my file and her boss and the Gm had taken over working on it. She then told me they pulled Ford model air bags from my Chevy Impala. Now the light has come on again. I do not feel safe or rust the dealership to fix it properly.

Since vehicle purchase in 2018 there is a shifting problem with the transmission. I have paid for shifter repairs and still the problem exist. While driving the car gets stuck in gear and hard to accelerate. The issue happens at various times without warning. There has been two instances that could have led to potential accidents. Upon spraking with and researching other impala owners, this is a common problem in the 3.6 engine Chevrolet Impalas but nothing has been done. The dealer has a plan to determine but it has always cost $1500+ to the customer.

answers to Questions from above 1. EVAPORATOR KIT 84409864 2. Not a safety issue to my knowledge. 3. Yes, issue was diagnosed and repaired at dealership. (Receipt for work - including part numbers will be attached with supporting documents) 4. No, no one outside of the dealership. 5. No warning lights but there was the smell of coolant in the cab of the car. Due to an issue with my 2018 Chevy Impala - V6 engine, I had to have the AC evaporator core replaced due to a leak (faulty part). Searching the NHTSA website, I found the below special coverage which seems to match my vehicle perfectly including the issue for which the special coverage was issued. I filed a claim with GM but continue to be told that my vehicle is not covered by this but no reason as to why it isn't covered. *Special Coverage N182186881 - Evaporator Core Icing, Leak *Quantity Part Name Part No. *1 EVAPORATOR KIT 84409864 This is concerning as a consumer as the issue and vehicle description matches the special coverage exactly, yet GM is stating that my vehicle is not covered. This issue clearly extends beyond the number of vehicles affected that was reported. Also, being replaced with the same part (part num) does give me pause that this will be an issue again in the future, costing consumers even more money and time.

The Evaporator core is leaking and a/c system is not operative. There is an outstanding report from your office, DCS4922, that outlines this condition perfectly. This report talks about a Special Coverage Adjustment #N182186881 Evaporator Core Icing, Leak, and an estimated number of vehicles involved. Since it is an estimated number of vehicles it means that GM doesn't know exactly how many vehicles are involved. It is my position that my vehicle should be included in the Service Adjustment. General Motors will not consider repair based on my VIN. This Special coverage addresses the exact issue I am experiencing. I have visited a Chevy Impala public forum and found there are others experiencing the same issue. Any help will be appreciated.

While driving or idling (car in D/M, both automatic and manual), the car will rapidly shift to park and then back to where the shifter was set, usually in a lower gear that slows the car down or prevents acceleration. The transmission or speed sensor could be an issue. This can happen in rapid succession 3-5+ times in a row, which has led to a drop in speed from 65 MPH to 40 MPH, especially dangerous at faster speeds on a highway or when deceleration is occurring more quickly, like going up a steep hill. I am unsure what indication there is for cars that are behind me, but they have had to slow down or pass me in some instances to avoid hitting me. If it happens while turning at a 2 way stop or on an entrance ramp, my car might not accelerate fast enough to merge into traffic. There have been no lights on the dash, and the dealer has not been able to identify the issue when I have taken it in.

While driving from work the car did a quick jerk and the STABILITRAK, ABS AND CHECK ENGINE LIGHT ALL CAME ON ALL AT ONCE. As I pulled into my workplace the car lost power to the engine completely while displaying ACTION REQUIRED ON THE LCD SCREEN. The brake and steering wheel became stiff and it was hard to control the vehicle. It took 10 minutes for me to regain power and control over the vehicle that again after leaving work stopped on the highway.

I noticed lately my car has trouble starting, especially after I get gas. Anywhere I take it, no one knows what it is. Literally someone said that I’m not holding the brake down when I’m starting it. I KNOW HOW TO START MY VEHICLE! It doesn’t want to start and sounds like a broke down Saturn when I start it. It takes like 20-30 seconds to start. ALSO that AC went out, I paid $700 AT Chevy, and then the AC went out again a few months later, again no one knows why. WTF!

I realize you stated the A/C is not a safety item but I read many complaint on this vehicle on the internet. I am a retired mechanic and the failure rate for evaporators is very low.
